" nTALLIc SIDING.

Application filed January 30, 1909. Serial No. 475,122.

To all tvhom it mat "concern: Be it known that LWILHELM' F. Bonnnss, acitizen of the United States, and residing in Chicago, in the-county ofCook and State of Illinois, have invented a new and useful Improvementin Metallic Siding, of which n the following isa complete specification.

t employed.

This invention relates to improvements in metallic siding and moreparticularlyto mef tallic siding for railway cars, tho'ughxobvi ou'slyit is equally well ada ted for'n'se'upon outer surface of which themetallic siding 'had been applied. Such siding has usually beenconstructed in largesheets, and for the purpose of strengthening thesame and affording the desired finish it has been proyided with deepgrooves or corrugations in which have been secured wooden strips orstays. Such construction is more or lessobjectionable, owing to theexpansion and contraction of the metal due to changes in temperatures,which causes the wooden strips to become loosened and to rattle when thecar is in motion.

The object of, this invention is to provide 7 a metallic sidingespecially adapted for use on railway cars, the st-rlps of which areadapted to be secured together by a lock seam or joint, which not onlyaffords the desired rigidity and prevents rattling, but also provides avery "neat exterior finish:

A further object of the invention, is to provide a metallic-*siding soconstructed as toprovide air spaces between the same and the outersheathing of the car, and in which the joints between adjacent'st-ripsare insured of a tight fit by reason of the resiliency of the metal.

\ The invention consists of the matters hereinafter described in thespecification, and more fully pointed out and defined in the appendedclaims.

In the drawings, Figure lis a fragmentary, horizontal section ofia' carbody provided with siding embodying my invention. Fig. 2 is afragmentary, perspective view of a strip of siding embodying myinvention.

As shown in said drawings: A-A indicate the posts or other uprightmembers of a car frame, and which, as herein shown, are

constructed-of beams, and are secured together by means of braces orgirders a. On

comprises a bead cl any preferred manner,

the inner face of said I beams, is secured in the inner sheathing B, andon the outer face thereof, is secured the outer sheathing B, which ispreferably constructed of sheet steel.

between the outer and inner sheathings may 4 be filled with any of theusual composition fillings, indicatedby C, which are ordinarilv useddnsuch structures to'afford a. nonconductor of heat. D On the outer' faceof the outer 1s. secured the siding, which is formed in strlps of thedesired width, and indicated as a whole by D. Said strips are preferablysecured in vertical position upon the car and each comprises a centralportion 03, which affords the outer face or finish, and an outersheathing and an inner looking or joint member, one on each marginthereof. The outer joint member metal back upon the tion cl, with thepart said portion left out of contact therewith, and the part inwardlyof said margin brought into contact with said portion, as shown at (P.The metal is then turned inwardly toward the sheathing B, as indicatedat d for a sufiicient distance to space the portion (Z the requireddistance from said sheathing, beneath and beyond the bead to provide theattaching flange d Said flange is provided with apertures 0Z throughwhich screws d may be inserted, to secure the strip tothe sheathing, asshown more clearly in Fig. 1. The inner joint member, which is providedinner face of said poron the opposite margin of the portiond, is

formed by turning the metal inwardly to provide a web dfparallel withand corresponding to the web (Z and then laterally in the plane of theflange d, but oppositely therefrom to provide a base portion 01 and thenoutwardly and laterally toward the web d to provide a tongue d adaptedto engage behind said head. The hook thus formed, is adapted to beinserted. in the space formed between the head 01, the portion 03 theweb (l and the flange 0?, as shown more clearly in Fig. 1.

In operation, one of the strips of siding is secured to the car body bymeans of the formed by folding the I beneath the margin of and is thenturned laterally 1 screws zilengaging through the apertures (1 andthehook or inner oint memberof the next adjacent strip is then insertedin the space formed behind the bead d, and as the strip is swung intoplace, the hook is forced into said space where it form a sulficientlytight joint to prevent the siding from becoming loosened by changes intemperature. The structure thus formed aflords a very neat exteriorfinish, and may be ap plied to other structures as well as car bodies onwhich it may be desired to place siding material.

Obviously, a siding constructed in accordance with my invention isadapted to not only afford a neat exterior finish, but to obviate allthe annoyance caused by rattling as is the case where wooden reinforcingstrips have been employed, and obviously, also many details of form andconstruction may be varied withoutdeparting from the principles of myinvention.

I claim as my invention:

1. A metallic siding strip comprising a central face portion, a hollowbead on the inner face thereof adjacent one lateral margin, areinforcing strip extending from one side of said bead parallel and inclose contact with the face portion, a spacing web extending inwardlyfrom one margin of said strip, an attaching flange extending from theinner margin of the web outwardly from beneath the bead and providing arecess between the same and said bead, strip and web, a web extendinginwardly from the opposite margin of the face portion, a base extendinglaterally from the inner v edge thereof, and a hooked portion extendmgupwardly from said base and laterally toward the face portion andadapted tofit' closely behind the bead on the adjacent strip.

2. A. metallic siding strip comprising a sheet of metal folded toprovide a central face portion (1, a hollow bead d beneath the margin ofsa1d face portion, a reinforcing stripd extending laterally from saidhead in close contact to the inner side of said face portion, a spacingweb d extending inwardly from the margin of said reinforcing strip, aflange d extending laterally from the inner margin of said spacing web.to a point beyond said bead, an inwardly directed web 01 on theopposite margin of said face portion adapted to abut against the bead onthe adjoining strip, a base portion 03 adapted to lie flat on the flangeJ and an outwardly and laterally directed tongue d adapted to lie inclose contact with the web 01 and strip d of an adjoining siding stripand abut at its edge against the inner side of the bead on said strip.

In testimony whereof I have hereunto subscribed my name in the presenceof two witnesses.
